JOHN B. DEEDS, OF TERRE HAUTE, INDIANA, ASSIGNOR OF ONE-HALF TO PETER J. KAUFMAN, OF SAME PLACE.

HYDROCARBON-BURNER FOR STEAM-BOILERS.

SPECIFICATION forming part of Letters Patent No. 364,993, dated June Application filed November 10, 1886. Serial No. 218,488. (No model.)

To all whom it may concern.-

Be it known that I, JOHN B. DEEDS, a citizen of the United States, residing at Terre Haute, in the county ofVigo and State of Indiana, have invented certain new and useful Improvements in Hydrocarbon-Burners for Steam-Boilers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appcrtains to make and use the same.

This invention has especial relation to steam-boiler furnaces, and my object is to maintain therein at a comparatively small is cost an intense heat resulting from the combustion of a hydrocarbon fluid with steam.

The following description, when taken in connection with the claims and the annexed drawings, will enable others skilled in the art to fully understand my invention.

In the annexed drawings, Figure l is a vertical longitudinal section taken centrally through a portable steanrboiler and its furnace, showing my improvement applied to it. Fig. 2 is a section in detail enlarged of the steam and water feed pipe and the cooks applied to it.

Referring to the annexed drawings by letter, A designates a horizontal tubular boiler; B, the fire-box; O,the grate, and D the pit be neath the grate. These parts may be CO11 strncted in the usual well-known manner.

In fact, my invention is applicable to any well-known steam boiler fire boxes. Upon 5 the grate G is supported a retort, E, which is preferably made of east or boiler iron, and which is provided with numerous jet-orifices or gasburners, c, as indicated in Fig. 1. Beneath this retort Eand the grate-bars C is 10- 4o cated a pan or receptacle, which is to receive oil or hydrocarbon fluid, which is ignited to initially heat the retort and generate a mixture of steam and hydrocarbon vapor, which, when the mixture is ignited at the burners,

creates an intense heat.

G designates a pipe, which communicates by means of a single-way cock, a, with the steam space of the boiler, and which also communicates with the space below the water line of the boiler by means of a branch pipe and three-way cock, I). The lower end of the pipe G enters the enlarged portion of a pipe, H, which forms a communication between an oil-receptacle and the retort or generator E. At thejunction of thepipe Gwith the pipe II is an injector, c, which operates on the principle of the Gifford injector for mixing the oil and steam, and introducing the same under pressure into the retort of a fine spray. In first raising steam the cock b is opened so as to allow a regulated supply of water from the boiler to mix with the oil, and thus provide for the formation of a mixture of steam and hydrocarbon vapor when the retort is heated, and produce a gaseous vapor,which, when 1gnited at the burners, will produce an intense heat. Vhen I have generated sufficient steam to operate the injector c, the cock b is turned and the water-supply cut off. The cock a, communicating with the steam-space, is then opened and the cock I), which I have above described as a three-way cock, is adjusted to allow steam only to pass from the boiler to the injector, which latter will now operate as above described.

It will be observed that the supply of oil and steannand the relative proportions there of which is necessary to give the best results, can be nicely regulated by adjusting the steam-cock. Iain thus able to utilize as a fuel any fluid hydrocarbon mixed with steam to supply hydrogen gas in suitable quantities to produce an intense heat in the furnaceehamber or fire-box.

I am aware that it is not new to inject hydrocarbons and steam into a boilerl'urnace and mutual] y decompose them while in a heated condition to furnish fuel for the generation of steam; also, that water and hydro carbon have been heated together initially to form a mixed vapor,which is decomposed and burned to commence the generation of steam, and the further generation of the steam kept up by supplying steam from the boiler in the place of the water.

The devices for effecting the process constitute the patentable novelty, which it i s th on ght the case presents.

Having described my invention I elaim- In a boiler-furnace, the combination,with a steam-boiler and fire-box, of a niimeronsly and oil -sn'ppiy pipes forming an injector,snb- IO perforated gas vaporizer or retort located in stantialiy as shown and described. the fire-box, the oil supply pipe communicat- In testimony whereof I affix my signature'in ing with this gas-vaporizer, apipe provided presence of two witnesses. 5 with a cock, forming a communication between the steam-space of theboiler and the oil- I JOHN DEEDS pipe, a. branch pipe having a cock, forming a Witnesses: communication between the water space of LOUIS D.
